[@ActRaiserTheReturned] Divine magic can basically be used for anything so long as you actually have enough magical power to perform the spell. Divine magic comes from prayer and worship. Arcane magic on the other hand is much more specialized, and comes from the inner self. It allows you to specialize in one or more areas of magic, and when combined with divine magic is extremely powerful.

Keep in mind that deities who focus on arcane magic, generally have less worshipers, and only use it to offset their lack of divine magic.
